# How to use the SMS inbox

> Read and reply to texts, understand segments, and recognize an unconfirmed send.

Texts to your number appear in **Inbox** with your other conversations. The **SMS** badge and business number show which number Eva will reply from.

## Reply to a text

Open the conversation, type plain text and check the counter before sending. A long message or some characters, such as emoji, may use several segments. Each actual segment costs **0.5 credit**; the counter is an estimate and the final charge uses the provider's count. Eva does not send photos or files through this channel. The composer allows up to **1,600 characters** per send.

If Eva shows **Unconfirmed**, it does not yet know whether the provider received the message. Do not resend just because of that notice: check the status later. If a send fails, read the reason in the conversation.

## When someone asks to stop texts

`STOP` stops texts to that person. `HELP` returns provider help. Eva also recognizes `BAJA` and `CANCELAR`; `START` or `ALTA` resume texts. Someone who asks only to stop promotions may still receive service replies. People who opted out are left out of campaigns.

If your number is still in A2P review, incoming texts may appear, but US-bound replies wait for approval. See [How to activate SMS](https://docs.goeva.ai/en/channels/sms/activate-sms.md).
